Henry originally hurt his knee in the first quarter against Philly on Dec. 29. He was later diagnosed with a bone bruise and an abnormality of the lateral meniscus.

The Kansas product recently went through his first extensive on-court workout on Sunday. Henry, however, experienced soreness in the area and was ruled out of Tuesday’s game vs. Cleveland. He will continue to do non-weight bearing exercises, but will not ramp up his workouts.

The Lakers embark on their annual Grammy road trip after the Cavs game, which covers seven games in 12 days. Henry will miss at Phoenix, at Boston, at Toronto and at Chicago. He will then be re-evaluated, at which point another prognosis will be assessed.

Xavier Henry has been ruled out of Tuesday’s game vs. Cleveland, according to Lakers team spokesman John Black.

On Sunday, Henry went through extensive on-court work for the first time since injuring his knee vs. Philly on Dec. 29, but experienced some soreness on Monday. He will continue to do non-weight bearing exercises, but will not ramp up his workouts. Prior to Sunday, Henry had been limited to what he could do with the training staff.

“I’ve been doing the pool, been doing all my treatments, been doing weights,” Henry said post practice on Sunday. “Today I wanted to see if I could jog up and down. We started with some jogs, some cuts, some defensive slides and regular-game stuff to see how I progressed. And we did a few different jumping things, and then after practice, I just wanted to get shots up and get myself into condition cause I never know when I’ll be able to play. I’m happy with what I got to do today because I haven’t gotten to do much.”

Henry was expected to see the doctor on Thursday, Jan. 9, which would have been 11 days since suffering what was diagnosed as a bone bruise and an abnormality of the lateral meniscus.

“I’d be lying if I said I’m 100 percent, but I’m (getting) there,” Henry said. “That’s all I’m trying to do – to get back as fast as possible. There’s still some issues that will only get better with time. I think I’m close to being back, and I’m not sure how long, but I’m feeling better.”

Henry suffered the injury late in the first quarter of the Lakers-Sixers game on Sunday, Dec. 29. He told reporters before Sunday’s game against Denver he would be re-evaluated on Thursday, which would mark 11 days since the injury occurred.

Because of a plethora of injuries to all of the Lakers primary ballhandlers and playmakers, the Kansas product had been filling in at point guard, both in a starting role and off the bench. Henry is averaging 10.1 points in 21.8 minutes per game.

Xavier Henry, who injured his right knee late in the first quarter of the Lakers-Sixers game, underwent an MRI on Monday morning that showed a bone bruise and an abnormality of the lateral meniscus. He will be re-evaluated in 7-10 days.

Kaman, who played just 10 minutes against Philly after tweaking his ankle at Utah, got treatment during practice and could play tomorrow, but will likely be limited, according to D’Antoni.

Xavier Henry, an afterthought of an offseason signing who has burst onto the Lakers scene, was told by coach Mike D’Antoni on Sunday morning that he’d be joining the starting line up.

“He’s played as well if not better than anybody,” said D’Antoni. “There’s no reason not to go ahead and do this.”

In three games, Henry is averaging 13.0 points on 40 percent field goals and 42.9 percent three-pointers, going off for 22 points against the Clippers in the lone win of the season. His numbers looked better before he went 0 for 6 against San Antonio on Friday, seemingly affected by a hard fall that produced nine stitches on his forehead. Regardless, he’s trying to keep his cool heading into his first start.

“I’m not too amped up,” said Henry. “I’m going to do the same things, attack it the same way.”

Henry’s ascension to the starting line up means somebody has to head to the bench, and that will be Nick Young. It’s D’Antoni’s hope that Young can play better with a more-energized second unit, and that it allows him a bit more room for his offensive game. Young has struggled in his first three games in purple and gold, hitting only 6 of 22 field goals (27.3 percent) with four rebounds and one total assist.

With Kobe Bryant still out, Henry is easily L.A.’s best at getting to the basket, something D’Antoni thinks could energize the starters. Tip off for Henry’s first chance to show his stuff as a starter: 6:30 p.m. at Staples Center against the Atlanta Hawks.
